Also for CV, I want to mention using diplomats for extra pressure. That was something I overlooked for quite a while. It is a nice boost, and something the player has good control over.
Actually, there are quite a number of World Congress proposals that can be very helpful to a culture victory (some require hotels, airports and NVC to convert culture to tourism):
Okay, I should have been more clear. It seems to me that, compared to everything else one must do for a peaceful CV, that control of the WC is a lower priority.
The AIs love most of those proposals. So almost every game I see Arts Funding, Cultural Heritage Sites, and Historical Monuments pass.
It seems like Cultural Heritage Sites helps the AI more than the player, but okay.
The AIs don’t seem to much like Natural Heritage Sites, but the player only has one of those half the time.
Controlling timing of IG can really smooth things out. But
winning IG (and WF) is more important than controlling their timing.
If you do have the WC locked up, then WI and especially WR are very nice. I just don’t think they are as important as a fast Internet. Do agree on that point?
All this is underscore the broad challenge of the CV. You need strong science (for Internet), strong hammers (for all those culture buildings), strong culture (duh), strong religion (for the culture buffs from faith buildings, and buying all the GP at the end), and then as much CS control as you can manage (keeping cultural CS allied being the first priority).
Locking up WC tight like it is a DiploVC (and you need WC locked up for WR), as compared to everything else one must do for a peaceful CV, seems like icing on the cake!
